Crop lack of boron correction of the main raw materials

1, industrial borax
Molecular formula is Na2B4O7? 10H2O, boron content of about 10.9%, colorless and transparent crystal or white powder. Incompatible with water, but soluble in hot water at 40 ℃, commonly used as domestic soil.
2, boron magnesium fertilizer
Molecular formula is H3BO3? MgSO4, boron magnesium fertilizer is boric acid residue, gray or off-white powder. Boron is mainly boric acid form, more difficult to dissolve in water, containing boron (B2O3) 0.4%, the domestic use as soil treatment.
3, boron magnesium phosphate
Born with acid and phosphate rock phosphate made of boron, containing effective boron (B2O3) about 0.6%. Domestic use as soil treatment.
4, boric acid
Containing more than 17% of pure boron (B), water-soluble, best to add boron, the best absorption. Can be mixed with most pesticide fertilizers.
5, four sodium octaborate
Containing pure boron (B) more than 20%, water-soluble, better boron supplement. Can be mixed with most pesticide fertilizers.
6, fluid boron (sugar alcohol boron)
By boric acid and diisopropanolamine, sorbitol xylitol and other substances through a special process of synthesis of a new type of foliar application of boron fertilizer. Boron (B) 160g / L, fast absorption, boron effect is excellent.
Boron fertilizer use technology
Boron participates in many important physiological activities and is an important nutrient necessary for crop growth and development. Suitable for all crop applications, increasing crop yields, improving crop quality, and improving crop resilience.
As a result of a variety of boron content, product purity, product quality difference between a large, so a variety of boron concentration using methods are not the same.
1, the domestic low content of boron application technology
Soil-based facilities? With bauxite per acre 0.5 ~ 1kg, and fine soil, phosphate fertilizer or nitrogen fertilizer evenly in the planting of transplanting ditch facilities or facilities. Boron mud as more basal fertilizer, about 15kg per acre, can be mixed with organic fertilizer application. Boron mud containing magnesium (MgO) 30 ~ 40% for the southern soil.
2, high content of instant boron application technology
Spraying micro-boron or Meng Bailong brand fluid boron, and water preparation of 0.1 to 0.15% aqueous solution, the crop seedling stage, bolting stage, bud stage, early stage of infancy, young fruit and other growth options spray 2 or 3 times. With the water chase and herbicides, insecticides, fungicides and other mixed application.
3, as many times as soon as possible
Boron in the plant's ability to operate poorly, should be sprayed as well. Cotton can be sprayed in the bud stage, spray every two or three consecutive 2 or 3 times as well. Fruit trees in the young fruit, full flowering spray better, can also be mixed with pesticides and 0.5% urea spraying.
4, soil-based facilities
Particulate boron can be applied to the soil, such as applying, applying, applying and spreading before the crop is sown. Apply 5 ~ 10g of each tree separately or with nitrogen, phosphorus, potassium fertilizer and organic fertilizer on fruit tree. Particulate boron is a completely soluble fertilizer whose large, granular physical structure makes it very advantageous in soil use. Has a relatively long-term, boron is not easy to leaching, not easy to cause soil boron poisoning.
5, soil topdressing
In the absence of soil-based application of boron or other boron fertilizers, in the late crop seedlings, to the soil topdressing boron particles 200g / mu, alone or with nitrogen, phosphorus, potassium fertilizer and organic fertilizer mixed with strip, Ditch Shi, Shi Shi, spreading and other methods for chase, chase watering.
6, Borosilicate boron and boron spray with
In general, soil is treated with primary particles of boron and sprayed with boron 1-2 times before flowering. The crops with high boron demand (rapeseed, cotton, peanut, fruit trees, vegetables, etc.) are improved in quality and the yield increase effect is very obvious.
